Abstract (en)
There is disclosed a fibrous sheet using a modified polyvinyl alcohol as a binder with which an aqueous solution containing a water-soluble organic salt, water-soluble inorganic salt and/or water-soluble boron compound is impregnated whereby wet strength of the fibrous sheet can be maintained. The fibrous sheet thus obtained is excellent in water-disintegratability and strength, and its water-disintegratability and strength are not lowered even at high temperatures. Furthermore, it is excellent in water-disintegratability even in cold water. <IMAGE>
